Kidneys became available on Tuesday morning and were taken to a local hospital. But when the hospital tried to contact the patient nobody could find her.

PSNI officers in north Belfast were asked to help track her down before the transplant opportunity was lost. They eventually located her and rushed her to hospital.

A police sergeant from Tennant Street took to Facebook to congratulate the response officers.

"(This) shows some of the good work done by our response officers that goes on in the background," the sergeant said.

Assistant Chief Constable Stephen Martin said: "This sort of work by officers often goes unseen. Our sincere best wishes go to the patient."

DUP Policing Board member Jonathan Craig said: "There has been a lot of talk about cutbacks and strain on police resources, but the officers are still doing whatever they can to save lives and keep people safe.

"Well done to the officers involved here and I wish this lady a full recovery."
